Kugwira ntchito kwa air compressor ndikofunikira mothandizidwa ndi zida zosiyanasiyana za valve. Pali mitundu 8 yodziwika bwino ya ma valve mu ma compressor a mpweya.
Valve yolowera
Valve yolowetsa mpweya ndi valavu yophatikizira mpweya, yomwe ili ndi ntchito zowongolera mpweya, kutsitsa ndi kutsitsa, kuwongolera mphamvu, kutsitsa, kuteteza kutsitsa kapena jekeseni wamafuta panthawi yotseka, etc. Malamulo ake ogwiritsira ntchito akhoza kufotokozedwa mwachidule monga: kutsitsa mphamvu ikapezeka, kutsitsa mphamvu ikatha. . Ma valve olowetsa mpweya wa Compressor nthawi zambiri amakhala ndi njira ziwiri: diski yozungulira ndi mbale yobwereza. Valavu yolowera mpweya nthawi zambiri imakhala valavu yotsekedwa kuti mpweya wambiri usalowe pamutu wa makina pomwe compressor yayambika ndikuwonjezera injini yoyambira pano. Pali valavu yolowera pamakina olowetsamo kuti muteteze vacuum yayikulu kuti isapangike pamutu wa makina pomwe makinawo ayambika komanso osanyamula katundu, zomwe zimakhudza ma atomization amafuta opaka mafuta.
Ma valve ocheperako
Valavu yocheperako yocheperako, yomwe imadziwikanso kuti valavu yowongolera, imakhala pamalo otulutsira pamwamba pa cholekanitsa mafuta ndi gasi. Kuthamanga kotsegulira nthawi zambiri kumakhala pafupifupi 0.45MPa. Ntchito ya valavu yochepetsetsa yochepa mu compressor ndi motere: kukhazikitsa mwamsanga kuthamanga kozungulira kofunikira kuti mafuta azigwiritsidwa ntchito pamene zida zayamba, kupewa kuvala kwa zipangizo chifukwa cha mafuta osowa; kuchita ngati chotchingira, kuwongolera kuchuluka kwa gasi kudzera muzosefera zolekanitsa mafuta ndi gasi, komanso kupewa kuwonongeka ndi kuthamanga kwa mpweya wothamanga kwambiri Mphamvu yolekanitsa yamafuta ndi gasi imabweretsa mafuta opaka kunja kwadongosolo kuti apewe kusiyana kwakukulu. mbali zonse za mafuta ndi gasi kupatukana fyuluta chinthu kuwononga zosefera; cheke ntchito ngati valve njira imodzi. Compressor ikasiya kugwira ntchito kapena kulowa m'malo osanyamula katundu, kupanikizika kwa mbiya yamafuta ndi gasi kumatsika, ndipo valavu yocheperako imatha kuletsa gasi kuchokera ku tanki yosungiramo gasi kuti isabwererenso mu mbiya yamafuta ndi gasi.
valavu chitetezo
Valve yachitetezo, yomwe imatchedwanso valavu yothandizira, imagwira ntchito yoteteza chitetezo pamakina a compressor. Pamene kupanikizika kwa dongosolo kumadutsa mtengo wotchulidwa, valavu yotetezera imatsegula ndikutulutsa gawo la gasi mumlengalenga mumlengalenga kotero kuti kupanikizika kwa dongosolo sikudutsa mtengo wololeka, potero kuonetsetsa kuti dongosololi silimayambitsa ngozi chifukwa cha kuchulukirachulukira. kupanikizika.
Valve yowongolera kutentha
Ntchito ya valve yoyendetsera kutentha ndikuwongolera kutentha kwa kutentha kwa mutu wa makina. Mfundo yake yogwira ntchito ndi yakuti kutentha kwa valve core kumasintha ndime ya mafuta yomwe imapangidwa pakati pa valavu ndi chipolopolo mwa kukulitsa ndi kugwirizanitsa malinga ndi mfundo ya kukula kwa kutentha ndi kutsika, potero Kuwongolera kuchuluka kwa mafuta odzola omwe amalowa m'malo ozizira a mafuta kuti atsimikizire kuti kutentha kwa rotor kuli mkati mwazomwe zimayikidwa.
Valve yamagetsi yamagetsi
Valavu ya solenoid ndi ya dongosolo lowongolera, kuphatikiza valavu yonyamula solenoid ndi valavu yotulutsa solenoid. Ma valve a Solenoid amagwiritsidwa ntchito kwambiri mu compressor kuti asinthe momwe akulowera, kuthamanga, kuthamanga, kuzizimitsa ndi magawo ena apakati.
Vavu yolowera mosiyana
Vavu yopingasa imadziwikanso kuti valavu yowongolera mphamvu. Valve iyi imagwira ntchito pokhapokha ngati mphamvu yokhazikitsidwa yadutsa. Vavu yopingasa yofananira nthawi zambiri imagwiritsidwa ntchito limodzi ndi valavu yowongolera mpweya wagulugufe. Pamene kupanikizika kwa dongosolo kumawonjezeka chifukwa cha kuchepa kwa mpweya ndikufikira kukakamiza kwa valve yopingasa yofanana, valavu yowonongeka imagwira ntchito ndikuchepetsa kutulutsa mpweya, ndipo mpweya wa compressor umachepetsedwa kufika pamlingo wofanana ndi dongosolo. Kugwiritsa ntchito mpweya kumakhala koyenera.
Valve yotseka mafuta
Valavu yodulira mafuta ndi chosinthira chomwe chimagwiritsidwa ntchito kuwongolera gawo lalikulu lamafuta kulowa pamutu wa screw. Ntchito yake yayikulu ndikudula mafuta obwera ku injini yayikulu pomwe kompresa yatsekedwa kuti mafuta opaka mafuta asapope kuchokera padoko lalikulu la injini ndi kubwereranso kwamafuta panthawi yotseka.
Valve yanjira imodzi
Valve yanjira imodzi imatchedwanso valavu yoyendera kapena valavu, yomwe imadziwika kuti valavu yanjira imodzi. Mu mpweya woponderezedwa, umagwiritsidwa ntchito makamaka kuteteza kusakaniza kwa mpweya wa mafuta kuti zisalowe mwadzidzidzi mu injini yaikulu panthawi yotseka mwadzidzidzi, zomwe zimapangitsa kuti rotor isinthe. Valavu yanjira imodzi nthawi zina siyitseka mwamphamvu. Zifukwa zazikulu ndi izi: mphete yosindikizira ya rabara ya valve ya njira imodzi imagwa ndipo kasupe wathyoka. Mphete yosindikiza kasupe ndi mphira iyenera kusinthidwa; pali chinthu chachilendo chogwirizira mphete yodindirayo, ndipo zonyansa za pa mpheteyo ziyenera kuyeretsedwa.
